Five years ago, as part of a plan to encourage citizens of Levaska to increase the amount of money they put into savings, Levaska’s government introduced special savings accounts in which up to $3,000 a year can be saved with no tax due on the interest unless money is withdrawn before the account holder reaches the age of sixty-five. Millions of dollars have accumulated in the special accounts, so the government’s plan is obviously working. Which of the following, if true, most seriously weakens the argument? A.A substantial number of Levaskans have withdrawn at least some of the money they had invested in the special accounts. 偶也错选了A,在仔细分析一下,估计选A的人是像我这么想的,存钱并且保持一段时间才是银行赢利的充分必要条件。政府要求超过$3000在65岁之前不要取出,如果我们认为这是此项计划成功的一个必要条件,那么A说取出了是不是就破坏了这个条件呢?其实不是,请注意看A说有相当一部分人取了一些钱出来,可是没说这些人没到65岁啊!所以即使有人取钱了,也不一定破坏了政府的要求“65岁之前不能取出”。所以比较一下D更万无一失的正确,所以选D:)
